I have a two frame frameset on a page - nav bar frame and content (the info for each page) frame. Each nav bar button remains in its down state when the corresponding content frame is loaded (providing it has been reached using the nav buttons). What I really want to to is get it working so that if I hyperlink from a content frame to another content frame - it will set a nav bar image for me so that the appropriate nav button goes into its down state (i.e. if I navigate without using the nav buttons the appropriate nav button will display its down state). I can do a simple swap image when the link is clicked to swap the image in the nav frame but then I am finding that it will often end up getting two of the nav buttons in a down state when I use the nav bar again.

Does anyone know a custom behaviour to do this or any other workaround
